- In his initial début, Ūhei's ears and tail were shaded a darker colour than the rest of his fur. This was however changed in later representations of him.
- In his anime début and again in Shippūden, Ūhei was initially coloured brown. This was corrected after a coloured manga image was released with him in it, giving him a red and white fur colour.
